For RMU, there would be several control options, depending on how the golem was made. Also, intelligence can vary widely, so it is up to you. The standard C&T golem is described thus: "They serve only their maker, responding do simple instruction (e.g., one-liners)." If the maker has no means to create or embed some real intelligence into the golem (and these existed at least as early as the RM2 Alchemy Companion), this is what he would be stuck with. The golem should be able to understand basic commands, including their implications ("protect me" implies both stopping attackers and carrying me away if the room catches fire), but you cannot give it a sequence of actions to follow or more than one condition ("Kill anyone who enters this room without wearing a red hat" should be okay).
